In the flux which is mixed with solder powder to produce the solder paste, an amount of phosphoric acid ester, which is adsorbed to a surface of a soldered portion during the soldering to form a film having hydrophobic quality is contained. It is preferable that an addition amount of phosphoric acid ester is not less than 1 mass% through less than 30 mass%. Further, it is preferable that the phosphoric acid ester is any one of (2-ethylhexyl) phosphate, monoisodecyl phosphate, monobutyl phosphate, dibutyl phosphate, monolauryl phosphate, monostearyl phosphate, monooleyl phosphate, tetracosyl phosphate or bis(2-ethylhexyl) phosphate.
